3 Description

The TSD5402-Q1 is a class-D sensor driving

amplifier, ideal for use in automotive and industrial

applications, including, but not limited to: resolverbased

motor control, braking systems, electric power

steering, servos, and flight control surfaces. The

wide operating voltage range and excellent efficiency

make the device ideal for applications that require

design flexibility. The integrated load-dump protection

reduces external voltage clamp cost and size, and the

onboard load diagnostics report the status of the load

through I2C. The integrated shorted load and open

load diagnostics allows systems to avoid external

implementations.
